Crystalline metallophosphates, their method of preparation, and use

ABSTRACT

A new family of crystalline microporous metallophosphates designated AlPO-92 has been synthesized. These metallophosphates are represented by the empirical formula
 
C c   + A a   + M m   2+ EP x Si y O z  
 
where M is a divalent framework metal such as magnesium, C is a cyclic organoammonium cation, A is an acyclic organoammonium cation, and E is a trivalent framework element such as aluminum or gallium. The AlPO-92 compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties suitable for carrying out various hydrocarbon conversion processes, as well as characteristics suitable for the efficient adsorption of water vapor in a variety of applications, such as adsorption heat pumps.

BACKGROUND OF THE INVENTION

This invention relates to a novel family of metallophosphates, collectively designated AlPO-92. They are represented by the empirical formula: C_(c) ⁺A_(a) ⁺M_(m) ²⁺EP_(x)Si_(y)O_(z) where M is a divalent framework metal such as magnesium, C is a cyclic organoammonium cation, A is an acyclic organoammonium cation, and E is a trivalent framework element such as aluminum or gallium.

Classes of molecular sieves include crystalline aluminophosphate, silicoaluminophosphate, or metalloaluminophosphate compositions which are microporous and which are formed from corner sharing AlO_(4/2) and PO_(4/2) tetrahedra. In 1982, Wilson et al. first reported aluminophosphate molecular sieves, the so-called AlPOs, which are microporous materials that have many of the same properties as zeolites, although they do not contain silica (See U.S. Pat. No. 4,310,440). Subsequently, charge was introduced to the neutral aluminophosphate frameworks via the substitution of SiO_(4/2) tetrahedra for PO_(4/2) ⁺ tetrahedra to produce the SAPO molecular sieves as described by Lok et al. (See U.S. Pat. No. 4,440,871). Another way to introduce framework charge to neutral aluminophosphates is to substitute [Me²⁺O_(4/2)]²⁻ tetrahedra for AlO_(4/2) ⁻ tetrahedra, which yields the MeAPO molecular sieves (see U.S. Pat. No. 4,567,029). It is furthermore possible to introduce framework charge on AlPO-based molecular sieves via the simultaneous introduction of SiO_(4/2) and [M²⁺O_(4/2)]²⁻ tetrahedra to the framework, giving MeAPSO molecular sieves (See U.S. Pat. No. 4,973,785).

Numerous molecular sieves, both naturally occurring and synthetically prepared, are used in various industrial processes. Synthetically, these molecular sieves are prepared via hydrothermal synthesis employing suitable sources of Si, Al, P, metals, and structure directing agents such as amines or organoammonium cations. The structure directing agents reside in the pores of the molecular sieve and are largely responsible for the particular structure that is ultimately formed. These species may balance the framework charge associated with silicon or other metals such as Zn or Mg in the aluminophosphate compositions, and can also serve as space fillers to stabilize the tetrahedral framework. A particular synthetic scheme utilizes multiple structure-directing agents in the same gel in order to direct the formation of multiple cages or cavities. This has been demonstrated for aluminosilicates, such as UZM-5 (U.S. Pat. No. 8,747,807), as well as silicoaluminophosphates, such as STA-20 (Turrina et al., Chem. Mater., 29, 2180 (2017)).

Molecular sieves are characterized by having pore openings of uniform dimensions, having a significant ion exchange capacity, and being capable of reversibly desorbing an adsorbed phase which is dispersed throughout the internal voids of the crystal without significantly displacing any atoms which make up the permanent molecular sieve crystal structure. Molecular sieves can be used for separation applications, in which certain species of a mixed liquid or vapor stream are captured within the pores of the molecular sieve, and others are excluded. Molecular sieves can also be used as catalysts for hydrocarbon conversion reactions, which can take place on outside surfaces as well as on internal surfaces within the pore.

As stated above, molecular sieves are capable of reversibly adsorbing and desorbing certain molecules depending on the adsorbate's size and the molecular sieve's internal pore structure. There are many applications where it is desired to adsorb water vapor, preferably in a reversible manner. One such application is an adsorption heat pump, which is a device that can be used to recover energy from exhaust or waste heat. As such, adsorption heat pumps can be utilized to maximize energy efficiency in an environmentally friendly manner. Molecular sieves can be useful materials to act as water vapor adsorbents in an adsorption heat pump due to their high capacity for water vapor. A description of the use of adsorbents in adsorption heat pumps can be found in U.S. Pat. No. 8,323,747, incorporated by reference herein in its entirety.

The type of molecular sieves used in adsorption heat pumps must meet certain requirements for optimal performance. A high overall capacity for water vapor is important, but most critically, they should fully desorb all adsorbed water at no greater than 100° C. Otherwise, too much heat must be applied to fully remove the adsorbed water from the micropores (i.e., the regeneration temperature is too high), thus requiring too high of an energy input. The majority of aluminosilicates (i.e., zeolites) have rapid uptake of water vapor at very low pressures (P/Po), which conversely leads to an unacceptably high regeneration temperature, despite a high overall capacity for water vapor. Aluminophosphates and silicoaluminophosphates have been shown to have more favorable adsorption characteristics for water vapor (see, for example, M. F. de Lange et al. Chem. Rev. 115, 12205 (2015); H. van Heyden et al. Appl. Therm. Eng. 29, 1514 (2009). In particular, the materials SAPO-34 and SAPO-5 (zeotypes CHA and AFI, respectively) have been shown to have particular utility as adsorbent materials in adsorption heat pumps (see U.S. Pat. Nos. 7,422,993, 9,517,942).

Another embodiment of the invention is a process for preparing the crystalline microporous metallophosphate molecular sieve described above. The process comprises forming a reaction mixture containing reactive sources of C, A, E, P, one or both of M and Si, and heating the reaction mixture at a temperature of about 60° C. to about 200° C. for a time sufficient to form the molecular sieve, the reaction mixture having a composition expressed in terms of mole ratios of the oxides of: aA₂O:bC₂O:cMO:E₂O₃ :dP₂O₅ :eSiO₂ :fH₂O where “a” has a value of about 0.01 to about 5, “b” has a value of about 0.01 to about 5, “c” has a value of about 0 to about 2, “d” has a value of about 0.5 to about 8, “e” has a value of about 0 to about 4, and “f” has a value from 30 to 1000.

Yet another embodiment of the invention is a hydrocarbon conversion process using the above-described molecular sieve as a catalyst. The process comprises contacting at least one hydrocarbon with the molecular sieve at conversion conditions to generate at least one converted hydrocarbon.

Still another embodiment of the invention is an adsorption process using the crystalline AlPO-92 material. The process may involve the adsorption and desorption of water vapor over AlPO-92 in an adsorption heat pump-type apparatus. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species. Removing contaminants may be by ion exchange with the molecular sieve.

DETAILED DESCRIPTION OF THE INVENTION

The invention involves a family of metallophosphate materials whose topological structure is unique. In their paper “Enumeration of 4-connected 3-dimensional nets and classification of framework silicates: the infinite set of ABC-6 nets; the Archimedean and σ-related nets,” Smith and Bennett state “To a first approximation, all silicates belonging to the ABC-6net family have x-ray diffraction patterns which can be indexed on a hexagonal prismatic unit cell with lattice parameters a˜13.0±0.3 Å and c˜p×(2.6±0.1 Å).” (See American Mineralogist, 66, 777-788 (1981)). This finding has subsequently been confirmed by others (see, for example, D. Xie et al. J. Am. Chem. Soc. 135, 10519 (2013)) as the ABC-6 family has expanded.

One particular composition of AlPO-92 indexes on a unit cell with hexagonal axes with lattice parameters a=13.127 Å and c=76.801 Å, which is suggests an ABC-6 net structure with the stacking sequence repeating every 30 layers along the c-axis (p=76.801/2.56=30). This is the first known example of an ABC-6 net structure with 30-layer repeats; hence the topology of AlPO-92 family of materials is unique. The instant microporous crystalline material (AlPO-92) has an empirical composition in the as-synthesized form and on an anhydrous basis expressed by the empirical formula: C_(c) ⁺A_(a) ⁺M_(m) ²⁺EP_(x)Si_(y)O_(z) where M is at least one framework divalent cation and is selected from the group consisting of alkaline earth and transition metals. Specific examples of the M cations include but are not limited to beryllium, magnesium, cobalt (II), manganese, iron(II), nickel and mixtures thereof. C is a cyclic organoammonium cation, and A is an acyclic organoammonium cation. The ratio c/a can have a value from 0 to about 1000, and the sum (c+a) represents the mole ratio of (C+A) to E and has a value of about 0.1 to about 2.0. The value of “m” is the mole ratio of M to E and varies from 0 to about 1.0, “x” is mole ratio of P to E and varies from 0.5 to about 2.0. The ratio of silicon to E is represented by “y” which varies from about 0 to about 1.0. E is a trivalent element which is tetrahedrally coordinated, is present in the framework, and is selected from the group consisting of aluminum, gallium, iron(III) and boron. Lastly, “z” is the mole ratio of O to E and is given by the equation: z=(2·m+c+a+3+5·x+ ⁴ ·y)/2.

Synthesis of molecular sieve materials often relies on the use of organoamino or organoammonium templates known as organic structure directing agents (OSDAs). While simple OSDAs such as tetramethylammonium, tetraethylammonium and tetrapropylammonium are commercially available, oftentimes OSDAs are complicated molecules that are difficult and expensive to synthesize. However, their importance lies in their ability to impart aspects of their structural features to the molecular sieve to yield a desirable pore structure. For example, the use of 1,4,7,10,13,16-hexamethyl-1,4,7,10,13,16-hexaazacyclooctadecane as OSDA has been shown to allow synthesis of STA-7, an aluminophosphate based material of the SAV zeotype (Wright et. al. J. Chem. Soc., Dalton Trans., 2000, 1243-1248); the use of 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane (‘Kryptofix 222’) led to the synthesis of AlPO₄-42 (Schreyeck et. al. Micro. Meso. Mater. 1998, 22, 87-106); MAPO-35, a magnesium aluminophosphate material with the LEV topology, is disclosed in U.S. Pat. No. 4,567,029 in which quinuclidine is employed as a structure directing agent; and in U.S. Pat. No. 4,973,785, the MeAPSO composition CoAPSO-35 is disclosed, which contains both cobalt and silicon in the framework in addition to Al and P and uses methylquinuclidine as the structure directing agent. Furthermore, there are instances in the prior art that teach the use of more than one OSDA in a molecular sieve synthesis. The OSDAs can be chosen such that there is a difference in their size and/or charge density, which can allow them to guide the formation of different cages or cavities. This approach has been demonstrated for aluminosilicates, such as UZM-5 (U.S. Pat. No. 8,747,807), as well as silicoaluminophosphates, such as STA-20 (Turrina et al., Chem. Mater., 29, 2180 (2017)).

The art shows that use of complex organoammonium SDAs often results in new molecular sieve materials. However, the synthesis of these complicated organoammonium compounds is quite lengthy and requires many steps, often in an organic solvent, thereby hindering development of the new molecular sieve material. Frequently, even for simple, commercially available OSDAs, the OSDA is the most costly ingredient used in synthesizing molecular sieve materials. Consequently, it would be economically advantageous to synthesize new molecular sieves from either commercially available organoammonium SDAs or SDAs which may be readily synthesized from commercially available starting materials. This has recently been demonstrated in an elegant fashion using simple aqueous chemistry to generate a novel family of organo-1-oxa-4-azonium cyclohexane compounds (U.S. Pat. No. 9,522,896), derived from morpholino-based compounds. The procedures described in U.S. Pat. No. 9,522,896 can be extended to the family of piperidine-based compounds as well. This procedure thereby allows the preparation of SDAs, such as unusual quaternary ammonium salts, from readily available starting reagents in a facile and practical manner. OSDAs prepared by the methods of the present invention are in aqueous solution and do not pose odor and flashpoint concerns. The result is the unprecedented ability to remove the cooling step typically required in the preparation of in-situ zeolite reaction mixtures and to avoid purification steps such as evaporation of organic solvent typically required in ex-situ preparation methods. The obtained organoammonium bromide salt can be ion-exchanged, either by reaction with Ag₂O or by anion exchange resins to yield the hydroxide form of the organoammonium compound, or used as the halogen salt directly. Finally, the resultant organoammonium compound can be used for the synthesis of a zeolite or molecular sieve.

The microporous crystalline metallophosphate AlPO-92 is prepared by a hydrothermal crystallization of a reaction mixture prepared by combining reactive sources of C, A, E, phosphorus, and one or both of M and silicon. A preferred form of the AlPO-92 materials is when E is Al. The sources of aluminum include, but are not limited to, aluminum alkoxides, precipitated aluminas, aluminum metal, aluminum hydroxide, aluminum salts and alumina sols. Specific examples of aluminum alkoxides include, but are not limited to, aluminum sec-butoxide and aluminum isopropoxide. Sources of phosphorus include, but are not limited to, orthophosphoric acid, phosphorus pentoxide, and ammonium dihydrogen phosphate. Sources of silica include, but are not limited to, tetraethylorthosilicate, colloidal silica, and precipitated silica. Sources of the other E elements include, but are not limited to, organoammonium borates, boric acid, precipitated gallium oxyhydroxide, gallium sulfate, ferric sulfate, and ferric chloride. Sources of the M metals include the halide salts, nitrate salts, acetate salts, and sulfate salts of the respective alkaline earth and transition metals.

One component of C may be an organoammonium cation prepared from the reaction of an aqueous mixture of a cyclic tertiary amine and an organic dihalide. Specific examples of cyclic tertiary amines include, without limitation, N-methylpiperidine, N-ethylpiperidine, N-methylhomopiperidine, N-ethylhomopiperidine, N-methylpyrrolidine, N-ethylpyrrolidine, N-methylmorpholine, and N-ethylmorpholine. Specific examples of organic dihalides include, without limitation, 1,4-dibromobutane, 1,5-dibromopentane, and 1,6-dibromohexane.

In one embodiment, the cyclic tertiary amine is N-methylpiperidine and the organic dihalide is 1,6-dibromohexane. In another embodiment, the cyclic tertiary amine is N-methylmorpholine and the organic dihalide is 1,6-dibromohexane. In another embodiment, the cyclic tertiary amine is N-methylpiperidine and the organic dihalide is 1,5-dibromopentane. In another embodiment, the cyclic secondary amine is N-methylpyrrolidine and the organic dihalide is 1,6-dibromohexane.

One component of A may be a tetraalkylammonium cation, represented as NR₄ ⁺. The R groups are chosen such that is the cation A is acyclic, and there may be multiple distinct R groups on the same quaternary nitrogen. A particular R group may have the formula C_(n)H_(2n+1), where n is a whole number ranging from 1 to 4, inclusive. Non-limiting examples of component A include tetramethylammonium, ethyltrimethylammonium, diethyldimethylammonium, methyltriethylammonium, tetraethylammonium, tetrapropylammonium, propyltrimethylammonium, butyltrimethylammonium, dipropyldimethylammonium, and methylethyldipropylammonium.

The reaction mixture containing reactive sources of the desired components can be described in terms of molar ratios of the oxides by the formula: aA₂O:bC₂O:cMO:E₂O₃ :dP₂O₅ :eSiO₂ :fH₂O

-   -   where “a” has a value of about 0.01 to about 5, “b” has a value         of about 0.01 to about 5, “c” has a value of about 0 to about 2,         “d” has a value of about 0.5 to about 8, “e” has a value of         about 0 to about 4, and “f” has a value from 30 to 1000. If         alkoxides are used, it is preferred to include a distillation or         evaporative step to remove the alcohol hydrolysis products.

The reaction mixture is reacted at a temperature of about 60° C. to about 200° C. and preferably from about 125° C. to about 175° C. for a period of about 1 day to about 21 days and preferably for a time of about 2 days to about 10 days in a sealed reaction vessel at autogenous pressure. The reaction vessel may be heated with stirring, heated while tumbling, or heated quiescently. After crystallization is complete, the solid product is isolated from the heterogeneous mixture by means such as filtration or centrifugation, and then washed with deionized water and dried in air at ambient temperature up to about 100° C.

The stable calcined AlPO-92 material can be characterized on an anhydrous basis by the empirical formula: H_(w)M_(m) ²⁺EP_(x)Si_(y)O_(z) where M is at least one metal cation of valence +2 selected from the group consisting of Be²⁺, Mg²⁺, Co²⁺, Mn²⁺, Fe²⁺, Ni²⁺, “m” is the mole ratio of M to E and varies from 0 to about 1.0, H is a proton, w″ is the mole ratio of H to E and varies from 0 to 2.5, E is a trivalent element selected from the group consisting of aluminum, gallium, iron, boron and mixtures thereof, “x” is mole ratio of P to E and varies from 0.5 to about 2.0, “y” is the mole ratio of Si to E and varies from 0 to about 1.0, and “z” is the mole ratio of O to E and has a value determined by the equation: z=(w+2·m+3+5·x+4·y)/2

The crystalline AlPO-92 materials of this invention can be used for separating mixtures of molecular species, removing contaminants through ion exchange and catalyzing various hydrocarbon conversion processes. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species.

The AlPO-92 compositions of this invention can also be used as a catalyst or catalyst support in various hydrocarbon conversion processes. Hydrocarbon conversion processes are well known in the art and include cracking, hydrocracking, alkylation of both aromatics and isoparaffin, isomerization, polymerization, reforming, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, dehydration, hydrotreating, hydrodenitrogenation, hydrodesulfurization, methanol to olefins, methanation and syngas shift process. Specific reaction conditions and the types of feeds which can be used in these processes are set forth in U.S. Pat. Nos. 4,310,440, 4,440,871 and 5,126,308, which are incorporated by reference.

The AlPO-92 materials may also be used as a catalyst for the conversion of methanol to olefins. The methanol can be in the liquid or vapor phase with the vapor phase being preferred. Contacting the methanol with the AlPO-92 catalyst can be done in a continuous mode or a batch mode with a continuous mode being preferred. The amount of time that the methanol is in contact with the AlPO-92 catalyst must be sufficient to convert the methanol to the desired light olefin products. When the process is carried out in a batch process, the contact time varies from about 0.001 hrs to about 1 hr and preferably from about 0.01 hr to about 1.0 hr. The longer contact times are used at lower temperatures while shorter times are used at higher temperatures. When the process is carried out in a continuous mode, the Weight Hourly Space Velocity (WHSV) based on methanol can vary from about 1 hr⁻¹ to about 1000 hr⁻¹ and preferably from about 1 hr⁻¹ to about 100 hr⁻¹.

Generally, the process must be carried out at elevated temperatures in order to form light olefins at a fast enough rate. Thus, the process should be carried out at a temperature of about 300° C. to about 600° C., preferably from about 400° C. to about 550° C. and most preferably from about 435° C. to about 525° C. The process may be carried out over a wide range of pressure including autogenous pressure. Thus, the pressure can vary from about 0 kPa (0 psig) to about 1724 kPa (250 psig) and preferably from about 34 kPa (5 psig) to about 345 kPa (50 psig).

Optionally, the methanol feedstock may be diluted with an inert diluent in order to more efficiently convert the methanol to olefins. Examples of the diluents which may be used are helium, argon, nitrogen, carbon monoxide, carbon dioxide, hydrogen, steam, paraffinic hydrocarbons, e. g., methane, aromatic hydrocarbons, e. g., benzene, toluene and mixtures thereof. The amount of diluent used can vary considerably and is usually from about 5 to about 90 mole percent of the feedstock and preferably from about 25 to about 75 mole percent.

The actual configuration of the reaction zone may be any well-known catalyst reaction apparatus known in the art. Thus, a single reaction zone or several zones arranged in series or parallel may be used. In such reaction zones the methanol feedstock is flowed through a bed containing the AlPO-92 catalyst. When multiple reaction zones are used, one or more AlPO-92 catalysts may be used in series to produce the desired product mixture. Instead of a fixed bed, a dynamic bed system, (e. g., fluidized bed or moving bed), may be used. Such a dynamic system would facilitate any regeneration of the AlPO-92 catalyst that may be required. If regeneration is required, the AlPO-92 catalyst can be continuously introduced as a moving bed to a regeneration zone where it can be regenerated by means such as oxidation in an oxygen containing atmosphere to remove carbonaceous materials.

The AlPO-92 materials of this invention can also be used as an adsorbent for water vapor. The adsorbent may be a component of an adsorption heat pump apparatus. Adsorbents used for adsorption heat pump purposes are desired to have a high capacity for water vapor, as well as a large crystallographic density. The crystallographic density of microporous crystalline materials is conveniently expressed in units of T-atom/1000 Å³. Generally speaking, adsorbents with a low density can be problematic since they would require a large volume of material to take up a given quantity of adsorbate. This can be troublesome if space is limited in the application. It is thus of interest to consider uptake capacity on a volumetric basis as opposed to a gravimetric basis.

As measured, AlPO-92 has superior uptake characteristics (on a volumetric basis) to both SAPO-34 and SAPO-5, which are preferred silicoaluminophosphate materials for use in adsorption heat pumps (see U.S. Pat. Nos. 7,422,993, 9,517,942). Thus, AlPO-92 could also be a preferred material for use in adsorption heat pumps.

The following examples are presented in illustration of this invention and are not intended as undue limitations on the generally broad scope of the invention as set out in the appended claims. The products will be designated with names that contain the suffix “−92” to indicate the “−92” structure and prefix that reflects the compositional nature of the product, such as “SAPO” for a silicoaluminophosphate, “CoAPO” for a cobalt aluminophosphate, and “MgAPSO” for a magnesium silicoaluminophosphate, etc.

The structure of the AlPO-92 compositions of this invention was determined by x-ray analysis. The x-ray patterns presented in the following examples were obtained using standard x-ray powder diffraction techniques. The radiation source was a high-intensity, x-ray tube operated at 45 kV and 35 mA. The diffraction pattern from the copper K-alpha radiation was obtained by appropriate computer-based techniques. Flat compressed powder samples were continuously scanned at 2° to 56° (20). Interplanar spacings (d) in Angstrom units were obtained from the position of the diffraction peaks expressed as θ where θ is the Bragg angle as observed from digitized data. Intensities were determined from the integrated area of diffraction peaks after subtracting background, “I_(o)” being the intensity of the strongest line or peak, and “I” being the intensity of each of the other peaks.

As will be understood by those skilled in the art, the determination of the parameter 2θ is subject to both human and mechanical error, which in combination can impose an uncertainty of about ±0.4° on each reported value of 2θ. This uncertainty is, of course, also manifested in the reported values of the d-spacings, which are calculated from the 2θ values. This imprecision is general throughout the art and is not sufficient to preclude the differentiation of the present crystalline materials from each other and from the compositions of the prior art. In some of the x-ray patterns reported, the relative intensities of the d-spacings are indicated by the notations vs, s, m, w, and vw which represent very strong, strong, medium, weak, and very weak respectively. In terms of 100×I/I_(o), the above designations are defined as:

-   -   vw=0-5; w=5-15; m=15-40: s=40-75 and vs=75-100

In certain instances the purity of a synthesized product may be assessed with reference to its x-ray powder diffraction pattern. Thus, for example, if a sample is stated to be pure, it is intended only that the x-ray pattern of the sample is free of lines attributable to crystalline impurities, not that there are no amorphous materials present.

In order to more fully illustrate the invention, the following examples are set forth. It is to be understood that the examples are only by way of illustration and are not intended as an undue limitation on the broad scope of the invention as set forth in the appended claims.

Example 1

909.0 g of water was weighed into a Teflon bottle. 508.3 g of 1,6-dibromohexane (99%) was added and the mixture was stirred. To the above mixture, 400.7 g of N-methylpiperidine (99%) was added slowly. Afterwards, the mixture was slowly heated to 50° C. with stirring. The mixture was held at this temperature for 24 hours and then allowed to cool, at which point the stirring is stopped and the solution harvested.

Example 2

1221.4 g of the solution from Example 1 was contacted with 326.5 g of Ag₂O in a round-bottom flask, which combined to form a grey opaque solution. The flask was placed under a high speed overheard stirrer, covered with aluminum foil, and stirred at room temperature for 1 day. The sample was filtered to remove the precipitated silver bromide and the final solution was sent for water analysis, which showed that the sample was composed of 70.0% water.

The gel was then stirred vigorously for 2 hours. The gel mixture was poured into a 45 cc autoclave and digested for 2 days at 170° C. The autoclave was tumbled during heating. Afterwards, the gel was cooled to room temperature, the product was isolated by centrifugation, and the solids dried at 100° C. overnight.
